摘要
阐述了膜生物反应器(MBR)在水处理方面的优缺点及膜污染的主要影响因素,总结了国内外关于膜污染及其数学模型的研究进展,归纳出膜污染模型的几种形式,并从膜本身的理化性质改变、混合液理化特性改善、操作条件优化等方面论述了减缓膜污染的方法及措施,介绍了几种膜清洗的方法及设计和操作过程中应注意的问题,提出了今后研究的重点和方向.
Characteristics of membrane bioreactors (MBR) used in wastewater treatment are reviewed and the major influencing factors on membrane fouling are discussed in this paper. The research on membrane fouling and its mathematical model are summarized, and several typical models are given as examples. Some measures to control membrane fouling are presented according to modifying the physicochemical properties of membrane material, improving the properties of mixed liquor of activated sludge, optimizing operation conditions. Cleaning of fouled membrane and related problems to be considered during design and operation of MBRs are introduced. Suggestion for the further study is also given.
